Complete the test and when a green circle shows tap it, when you see a button “pass” click it. At the end it should fail so just click the “fail” button when there is no “pass” button anymore.
Start the test by clicking "start", then hold the green circle with your finger till the test finishes. On the last test it will fail so just click on "fail".
Repeat 3 times and try adding a fingerprint, if fingerprint still does not work just restart and retry again.
